What is the expected behavior?

subtree can be treated by block, providing nodes in breadth first search (bfs) order.

root = MODEL.find_root
root.subtree.bfs.each do |node|
  # do something
end

What is the expected behavior?

subtree can be treated by block, providing nodes in depth first search (dfs) order.

root = MODEL.find_root
root.subtree.dfs.each do |node|
  # do something
end

What is the expected behavior?

add_parent and create_parent should create a parent, and the parent include only given children.

What is the current behavior?

A parent created by this method includes nodes which are not given as an argument:
so far, the area is calculated by the following codes:

left  = children.max {|c| c.l_ptr}.l_ptr
right = children.min {|c| c.r_ptr}.r_ptr

What is the use-case or motivation for changing an existing behavior?

A has B, C and D as children (,and they are stored in this order in DB).
When B and D will have a new parent E, E can't help including C due to the current implementation.

Which versions of gem, ruby, rails or middlewares are affected?

any

Is there anything else we should know?

no

What is the expected behavior?

To get direct parent and children by:

@node.parent
# => parent node of @node

@node.children
# => child nodes of @node as ActiveRelation

What is the expected behavior?

after copy/move, the tree should have correct structure as tree, that is,
all the left and right pointers have unique values each.

What is the current behavior?

after copy/move multi-layered subtree, the tree seems to be destroyed

What are the steps to reproduce?
